. WEATHER STRIP.

Application filed April 23,

This invention relates to a weather strip of that type consisting of a strip of felt or the like which is partially encased.

Heretofore weather strips of this type have been objectionable for the reason that when used in connection with a railway car door, the carrying of baggage or lading through the door would frequently result in the baggage or lading coming in contact with the edge of the casing and distorting or tearing the casing from the weather strip. It is primarily an object of this invention to overcome this defect in so fashioning the contour of the outer face of the casing so that baggage and lading will not catch upon the edge of the casing.

The invention comprises the novel structure and'combination of parts hereinafter described and more particularly pointed "out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the dif ferent views:

On the drawings:

Figure 1 is a fragmentary outside elevational view of the weather strip involving this invention.

Figure 2 is a fragmentary sectional view illustrating the application of the weather strip to a car door.

Figure 3 is an enlarged fragmentary sectional view similar to Figure 2, showing the same application of the weather strip.

As shown on the drawings:

As illustrative of this invention there is shown a strip of felt 1 or the like which is partially encased in a metal casing consisting of a flat bottom or rear wall 2, and an outer or front wall 3 which is integrally formed with the rear wall. The outside or front wall 3 is formed of a plurality of arcuate surfaces. In the present instance, two arcuate surfaces 3 and 3 are illustrated with a line of indenture 3 between the arcuate surfaces. It will be noted that the free or outer edge of the arcuate surface 3 is turned inwardly in accordance with the curvature of the arcuate portion. This curvature may be increased or decreased as desired, The greater the curve of the arcuate portion 3", the more will the free edge be turned inwardly and indent the strip of felt. It will also be appreciated that 1927. Serial No. 185,930.

the arcuate portion?) curved shoulder.

This weather strip as described is frequently used in connection with a railway car doorand in Figures 2 and 3 there is illustrated an application of the invention. In referring to said figures, it will be noted that the door jamb 4 is provided with a vertical strip 5 upon which the weather strip is fastened. A portion of the door 6 is shown in contact with the weather strip. In carrying baggage or lading through the car door it has frequently happened that the baggage or lading would catch the forward or free end of the weather strip with the result that the edge of the casing would be distorted or pulled outwardly in the prior art structures. This forms a sloping or is, however, avoided in the present invention on account of the arcuate shoulder 3 involving the inturned edge 3 The baggage and lading" cannot catch the free edge?) on account of its inward deflection. The baggage or lading will merely strike the arcuate shoulder 33 and glance off.

It will also be apparent that the indenture 3 forms a V-shaped wedge lock that has a firm wedging and binding effect upon the felt strip 1. The nail holes are punched in the indenture 3 as shown in Figure 1, and on account of the indenture, the punch will not pull out or distort the casing when said punch is being pulled out as frequently occurs in punching a level surface. Further, the indenture 3 together with the arcuate portions increases the strength and rigidity of the outer flange of the casing and since the securing nails are driven in the line of indenture, and since the outer portion 3 is arcuate, there is little liability of the edge 3 springing outwardly when the strip is being nailed in position as would occur in a flat strip. Consequently, the edge 3 will always maintain its inwardly directed arcuate position. It will be appreciated that if a flat or substantially flat sheet were nailed upon a post, the outer edges would tend to spring outwardly away from the post. This would be exceedingly objectionable in a weather strip, especially of such a type as herein disclosed. However by forming or stamping a groove such as the line of indenture 3 in the strip and driving the nails through holes in such groove, there will be no outward springing of the outer edge. Consequently, the groove or line of indenture 3 is important in that it not only forms a V-shaped wedge lock for the felt strip but it also prevents springing of the free edge of the strip in nailin From the foregoing, it will be appreciated that a novel and important improvement has been made in the type of weather strip herein described. It might be mentioned that railroad companies found the old weather strips of the prior art so unsatisfactory due to the fact that the casing thereof was constantly beingtorn oil by the ladingor baggage that they were dispensing with the use thereof. The present invention has, however, overcoi'ne this defect in a very eflicient manner and has made this type of weather strip a success for railway cars, whereas in the past it has been a failure.

I am aware that many changes may be made and numerous details of construction maybe varied through a wide range wi hout departing from the principles of this inventionand I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art,

I claim as my invention:

1. In a weather strip, a flexible strip, a metal casing partially enclosing the same, said casing having a bottom wall and an upper wall having a longitudinal indenture for locking said flexible strip between said walls, the portion of the upper wall forward of said longitudinal indenture being slightly arcuate for deflecting material for preventing tearing of said upper wall from said flexible strip. V

2. In a weather strip, a flexible strip, a metal casing partially enclosing said flexible strip, said casing having a lower wall and an upper wall having a longitudinal indenture within the confines of the lower wall for looking said flexiblestrip between said walls and forming a nailing line.

3. In a weather strip, a flexible strip, a casing partially enclosing said flexible strip, said casing having a lower wall and an upper wall witha longitudinalindenture for looking said flexible strip between said walls, said upper wall also having a downwardly sloping front margin for deflecting material for preventing tearing of said upper wall from said flexible strip.

4, In a weather strip, a flexible strip, a metal casing partially enclosingsaid flexible strip, said casing having a flat bottom wall and an indented upper wall contacting said flexible strip throughout the width. of such upper wall; the free edge portion of said upper wall having a slight downward curve for deflecting material to prevent tearing of said upper wall from said flexible strip.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County,

Illinois.
